Kidō Senshi Gundam: Senjō no Kizuna (機動戦士ガンダム 戦場の絆, lit. Mobile Suit Gundam: Bonds of the Battlefield), is a Japanese arcade game set in the original Gundam universe (Mobile Suit Gundam). The game was created by Bandai Namco and Banpresto and was released late 2006. Play involves stepping into a P.O.D. (Panoramic Optical Display) and doing battle with other players across Japan.

The game was launched in Japan on 7 November 2006 with arcades usually equipped with 4 pods (some amusement
centers have more). Battles take place online across Japan against other players from opposing factions (全国対戦).

In this game, players become pilots of giant robot mobile suits from the anime series. Pilots play through two battle scenarios lasting a total game time of ten minutes. Pilot cards are purchased at the game's pilot terminal. A large monitor replays the last battle and an angled touch screen user interface is used to manage pilot battle data. Almost everything is in kanji, hiragana, and katakana.

The pilot terminal updates pilot cards before and after games are played. Pilots can walk away from an end game for a week and not insert their pilot cards into the pilot terminal(data from the last battle is saved on the card inside the pod). However, if a pilot card is not used for a long period, such as a few months to a year, the pilot card unit icon (The battle station's city/town location where the pilot card was first generated) is erased and a new unit icon is printed on the card at the pilot terminal it is re-inserted. For example, if a player buys a pilot card at a Kawasaki game center, the pilot terminal prints the Kawasaki game center's icon on that pilot card. If the card goes dormant for months, and the player goes to a Yokohama game center, inserts his/her pilot card at that game center's pilot terminal, the Kawasaki game center icon is erased, and the Yokohama game center icon is printed on the card. All other data may still be saved on the card-all unlocked mobile suits, upgrades, and weapons are still saved on the card (some data traits are reset-see the Japanese website for recent version and game changes).

Most game centers have a sign up sheet near the pilot terminal. Players are seated according to the time and play level they signed in. Beginning pilots should always circle the beginner kanji on the sign up sheet. This system allows team players and advanced players to decide whether to play the next game with beginner players, or pass and wait for another game window. Another reason why advanced players do not play with beginners is that some advanced players do not want to risk lowering their online ranking in the game. Advanced players do not have the time or money to maintain a high ranking in the game, so reaching and holding a high ranking is very important to them.

The game plays through a reservation system. All pods in a game center are interlinked. Players can opt to launch simultaneously with their friends or with other players who have also opted to launch at the same time, in the same game center, though it is not required. If players are not alone and launch with other people in the same arcade, voice chat becomes possible between the players. Pilots run two battle scenarios per game, average game time lasts 10–15 minutes and based on game center location, updates, time and popularity, makes for long waiting lines.

The game POD is large and has an adjustable seat, surround sound speakers, projector screen, headset jacks(red and green), hand control sticks and foot pedals. Each POD is equipped with headset jacks for in-game communication between players (pilots may bring their own headsets, but forget to take them when the game is over). The pilot inserts his/her pilot card into the card slot and inserts 100 or 500-yen coins to begin gameplay. The battle scene point of view is from inside the mobile suit, the overhead projector displays three panels onto the inner dome screen about 1m away from the pilot's seat (a little longer than arm's length). Inside the pod entrance door, there is just enough space to stand another person on the side, or place a backpack or gymbag

The Hong Kong launch of the game (at Rev. 1.01) was on 19 April 2008 at Causeway Bay's Wonder Park Plus.[1] As of spring 2009 the cabinets are available in 5 more arcades in Hong Kong, and had been featured during the C3 HK exhibition in April. Machines at all three locations are at Rev. 1.01 and the linked play between all three arcades are possible, though the version difference prevents any overseas arcades to be compatible with the Japanese version.

Users accessing the official websites are recommended to access the Hong Kong website for the Cantonese and English translations, and the Japanese website for the Japanese release.

The game was introduced to Taiwan on 28 July 2009, with 8Pods in Chung-Li and 8 in Taichung.
Later on in November, additional 4POD sets was added in Taipei and Shin-Chu.

Singapore has also brought in 8 pods which are available at Bugis TKA arcade and 4 pods in Zone X Ang Mo Kio HUB. it has been activated on 31 August 2009. *update* - as of 21 Feb 2010, all operators in Singapore have removed the units.

As for October, 2009, All three regions (Hong Kong, Taiwan and Singapore) share the same revision(1.07),
and players are able to connect overseas in these regions.

As of 24 November 2010, both Hong Kong and Taiwan regions upgrade to Japanese revision 2.18. From this point, linked play between Japan and oversea regions(Hong Kong and Taiwan) has become available.

Typical Gameplay: After these four missions, battling on the main maps becomes possible. Opponent matching is done through ranks, so players will fight players of relatively similar rank. However, should 3 high rank players launch with 1 low rank player, matches may become advantageous as the opposing team may be composed only of low rank players. After every game session, players go to the pilot terminal to receive the points they earned in battle and any new mobile suits or upgrades.

Each session consists of two matches, each 250 seconds long. Dealing damage in-game gives points to the pilot while destroying an enemy mobile suit gives further points depending on what suit was destroyed. More points are awarded for higher valued mobile suits, while if a player is destroyed, some points will be deducted from his/her score. Additionally, pilots receive small boosts of points when allies destroy mobile suits. Bars on the left side of the screen (blue for Earth, red for Zeon) display the overall battle strength of the teams. Destroying an enemy depletes the bar according to the cost of the mobile suit that was destroyed. Additionally, should a team's base (kyoten 拠点) be destroyed, a considerable amount of bar is depleted. If the bar is completely depleted before the end of combat, that side loses and the other wins the match. A draw game occurs if both bars are even at the end of the time limit.

The mobile suits featured in the game are based on units that appeared in the series. The game had divided these suits into five categories, based on the optimal range for combat. These include melee, short, medium, long range support and sniper units.
